Three more cracking pens from your stable Ben.
I see you're still getting it in the neck for your photo staging. Personally I don't have a problem with your background. Your lighting is not at all bad either - maybe a little glaring in one or two spots, but there again you are showing us work as it comes off the lathe - so I don't have a problem with your lighting either.
However, if you want a really cheap solution to silence your critics, you could pop into your local wallpaper merchant and pick up a roll of good quality lining paper. It's very nearly pure white, and is really handy as a background within easy arms reach, for firing off any quick "this is what I've done today" photos. That and a "grey card", (which we talked about on the phone the other day), and you are home and dry Ben. Critics are silenced.
